BENJAMIN F. MASON, OF HOT SPRINGS, ARKANSAS, ASSIGNOR 0F ONE-FIFTH T0WILLIAM L. BISHOP, OF HOT SPRINGS, ARKANSAS.

COTTON-CHOPPER.

To all whom it may concern:

Be it known that I, BENJAMIN E. MASON, a citizen of the United States,residing at Hot Springs, in the county of Garland, State of Arkansas,have invented certain new and useful Improvements in Cotton-Choppers;and l do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the saine.

The invention relates to cotton choppers and more particularly to theclass of single row cotton chopper attachments for plows.

The primary object of the invention is the provision of a cotton chopperattachment in which the rotatable chopper blades are disposed in lateralspaced relation to the path of travel of the ground or supporting Wheelso that a row of cotton plants may be thinned out and the ground wheelwill travel atone side of the row and also the share of the plow willenter the soil and make a furrow along one side of the row of growingplants for the proper cultivation thereof.

Another object of the invention is the provision of a cotton chopperattachment which may be conveniently attached to the beam of an ordinaryplow so as to be operated in connection with the latter.

A further object of the invention is the provision of an attachment ofthis character in which growing plants adjacent to fences may be thinnedout so as to leave the plants in bunches or hills as the machine isadvanced through a field.

A still further object of the invention is to generally improve thisclass of devices so as to increase their utility, durability andefliciency.

lith these and other objects in view, the invention consists in theconstruction, combi nation, and arrangement of parts, as will behereinafter more fully described in detail, illustrated in theaccompanying drawings, which disclose the preferred form of embodimentof the invention, to enable those skilled in the art, to practice theinvention, and as pointed out in the claim hereunto appended.

In the drawings z--Eigure 1 is a side ele vation of a plow with theinvention applied thereto. Eig. f2 is a top plan View thereof. Fig. 3 isa sectional view on the line 3 3 of E ig. 1. Fig. 4c is an end elevationof the Specification of Letters Patent.

chopper blade supporting plate or disk with the blades attached thereto.F ig. 5 is a rear elevation.

Similar reference characters indicate cor responding parts throughoutthe several views in the drawings.

Referring to the drawings by numerals, 6 designates generally a` plowwhich is of the ordinary well known construction comprising a main beam7, to the rear end of which is lixed a forwardly inclined standard 8,carrying at its lower end a plow blade or share 9, and to the main beam7, are connected upwardly diverging handle bars 10, the same being alsoconnected by a cross rung 11, to the upper ends of the standard 8, so asto maintain the said handle bars rigid.`

The cotton chopper attachment comprises hangersflQ, correspondinglyshaped to each other and disposed against opposite sides of the plowbeam 7, and detachably secured j thereto by bolt members 13, connectingthe hangers 12, above and below the plow beam.

These hangers have j ournaled in their lower ends an axle 14, to one endof which is fixed a ground or supporting wheel 15, while its oppositeend has fixed thereto a beveled gear 16, through the medium of whichmotion is transmitted to the chopper blades as will be hereinafter morefully described.

Detachably connected to the plow beam 7, a slight distance in advance ofthe hangers 12, is a laterally projecting U-shaped bracket 17, havingrising centrally from its cross connecting piece an extension 18,through which are passed bolt members 19, disposed above and below theplow beam 7, and also through a strap plate 20, so that in this mannerthe bracket is securely fastened to the plow beam. Journaled in thebrackets 17, at right angles to the axle 14, is a driven shaft 21, tothe rear end of which is fixed a beveled pinion 22, the latter meshingwith the beveled gear 16, on the axle 14, and to the forward end of thisshaft 21, is fixed a disk 23, to the front face of which are se curelyfixed by detachable staples 24, substantially U-shalped laterallyprojecting blade supporting arms 25, to the free ends of which are ixedchopper blades 26, actuated through the medium of the driven shaft bythe supporting or ground wheel.

It is apparent-that by the employment of the bracket 18, the chopperblades 26, are disposed a considerable distance to one side of the plowbeam 7, andthe ground or sup to the beam in advance of the hangers and fporting wheel of the attachment, so that the extending laterally fromsaid beam, a shaft latter will travel at one side of a row of journaledinthe bracket at right angles to 15 Y growingr plants. the axle andhaving a pinion at one end 5 What is claimed iszmeshing with thegear anda chopper fixed The combination with a plow having a to the opposite endof the shaft. share, of hangers detachably connected to In testimonywhereof, I aflix my signathe plow forwardly of the share, an axle ture,in presence of two witnesses.
